Polypropylene (PP) is a semi-crystalline thermoplastic material, with a continuous use temperature range of -4° F (-20° C) to 212° F (100° C). It is categorized as a standard material, and offers excellent toughness, chemical resistance, and processability.
Highly chemical resistant
Superior resistance to stress cracking
Suitable for contact with foodstuffs
Good electrical insulation properties
High surface hardness
Very low water absorption
